Assessment and modelling of GHG balance of peat extraction sites and abandoned or rewetted peat extraction sites

On the basis of aggregated databases and additional collected data, a methodology for estimating GHG emissions from peat extraction areas belonging to the wetland category, including rewetted former peat extraction areas, will be developed at the Tier 3 level, guidance material and a plan will be prepared for the further monitoring of water levels and other factors necessary for modelling GHG (CO2, CH4 and N2O) flows. The study consolidates public datasets of GHG fluxes from previous surveys of peat extraction areas belonging to the wetland category, including rewetted former peat extraction areas, for the purposes of greenhouse gas (GHG) inventory according to LULUCF requirements. Additional GHG measurements will be performed in naturally revegetated and rewetted former peat production areas to assess vegetation and water regime recovery and gas fluxes dynamics and to model the GHG emissions according to the peat decomposition rate and following the production cycle of peat extraction.
